如何强制用户下载（另存为对话框）刚刚生成的文件？

Question

I'm generating a file using the query

SELECT * INTO OUTFILE " . "'c:/myfile.csv'" . " FIELDS TERMINATED BY ','  LINES TERMINATED BY '
' FROM sample

My file is now in C:/myfile.csv. I want the user to download the file. How can I achieve this?

Answer 1

You could :

• Send an HTTP header, to indicate the kind of data you're sending, and that it should be downloaded to a file.
• And, then, send the content of that file.

In PHP, something like this should do the trick :

header('Content-Disposition: attachment; filename="my-file.csv"');  // The name which will be suggested to the user
readfile('c:/myfile.csv');  // outputs the content of the file
